Everyone is fighting for survival, are you shopping for free in the supermarket?

The second option is gray. Only after the building core is upgraded can the basement be upgraded.

But no matter what, Ye Qiu realized the rarity of the building core!

You only need to consume resources to upgrade the building quality, which will save a lot of upgrade drawings!

Click on the upgrade interface, the upgrade of the basement building core requires stone (green) * 20, "wood (green)" * 20, which is basically half of the materials for building the basement.

It is very worthwhile, but in order to build the wall, Ye Qiu now has no green quality stone, and there are not many green quality materials circulating in the market. Ye Qiu can only choose to buy it, and he will probably have to wait until he goes to bed at night to collect all the stones.

However, the next upgrade may require blue quality stone, which is even more difficult to find... Ye Qiu has begun to worry.

Blue quality means transcending the scope of normal materials. No matter how high the quality of things on the mother planet is, it can't reach this level, but with the current level of the survival world, mining is a big problem...

Forget it, it's easier to collect materials than to find better building drawings.

Walking out of the basement, Ye Qiu glanced at the fence outside.

He now regretted using the building core on the garrison without hesitation on the first day.

It only increased the space a little bit, and the health of the building by more than ten points. Compared with the buildings that can be upgraded infinitely, it is simply a blood loss!

Sighing in his heart, Ye Qiu walked to the stone fence and continued his unfinished work.

An hour later, Ye Qiu finally completed the installation of the stone fence, and the area of ​​Ye Qiu's garrison finally reached 2,500 square meters!

Cleaned the grass between the stone fence and the wooden fence, especially took back all the traps.

Then, Ye Qiu made a barbed wire to wrap around the stone fence, dug a trap pit inside the fence, and made more traps evenly scattered outside the fence.

After this set of work, it was already dark.

In the golden afterglow, Ye Qiu stood in the small yard and checked his garrison.

In order to reach his house, the other party needs to cross the grass with the trap, then break the stone fence with barbed wire, cross the trap pit behind the fence, then break the wooden fence with barbed wire, and cross the trap pit behind the wooden fence.

With such defense, Ye Qiu estimated that ordinary high-level fog beasts may not be able to hit his door!

Even the attackers who can fly have to face the barbed wire on the stationed ground!

"Not bad, not bad, the safety quality has been improved!"

Ye Qiu nodded with satisfaction, and at the same time took out a few wooden sticks from his backpack and inserted them into several nodes in the yard.

At the same time, hang oil lamps on these wooden sticks.

When the fog beast attacks, Ye Qiu can light the oil lamp in the yard, and then use a crossbow to attack the fog beast from a distance!

In the past, because the durability of the wooden fence was very low, Ye Qiu generally only used it as a warning line.

But the durability of the stone fence is several times that of the wooden fence, and Ye Qiu can completely rely on the stone fence for defense!

After completing these tasks, Ye Qiu finally remembered another reward from fighting the lion.

[Fertilizer Manufacturing Diagram (Blue)]!

Fertilizer, at first glance, is something that plays an important role in plant growth.

As a reward in the survival world, Ye Qiu has even greater expectations for it!

Crushing the blueprint, the system immediately showed the method of making fertilizer.

Ye Qiu looked at it and found that there were not too many restrictions on the manufacture of fertilizer. Biological feces, wood chips, fruit cores and other garbage, animal blood, flesh and internal organs, etc. can all be used to make fertilizer.

Looking at the warehouse, Ye Qiu processed the useless materials such as "Unknown Biological Remains (White)" and "Leaves (Blue)", and soon got two large bags of fertilizer.

Ye Qiu identified the fertilizer produced by the system.

——

[Fertilizer (Blue)]

[Description: Nutritious organic fertilizer, applied to crops will appropriately reduce their growth time, be careful not to use too much! 】

【Features: Non-persistent (In the same amount of time, more fertilizer can be applied without worrying about burning seedlings)】

——

Sure enough, just like the fertilizer in the game, it can speed up the growth of crops!

With the addition of the blue quality planting box, the growth rate of many crops has already reached a staggering level, and with this fertilizer, Ye Qiu feels that it is not a dream for crops to mature in two days!

It was already dark, Ye Qiu cooked the fog beast meat in the pot, and carried the fertilizer to the planting box.

Light an oil lamp, and under the dim light, the green seedlings in the six planting boxes looked vibrant, which made people feel happy.

Grabbing a handful of fertilizer, Ye Qiu evenly sprinkled it on the soil.

I saw a faint glow, and the light green fertilizer gradually disappeared from Ye Qiu's vision, and instead, the seedlings in the planting box grew visibly!

The small orange tree suddenly jumped, and Ye Qiu even saw one or two white flower buds.

The star berries have grown densely, filling up the planting box.

The most outstanding one is the sweet potato, whose green leaves are densely covering the planting box, almost spreading to the nearby planting boxes!

Ye Qiu opened the system and looked at their maturity time.

You don’t know until you see that the sweet potatoes are already ripe!

The harvest time of other crops has also been reduced, about two days.

About one day later, you can harvest the star berries, and three days later, you can harvest potatoes!

Such rapid progress made Ye Qiu overjoyed. Although sweet potatoes and potatoes are ordinary crops, star-drop berries are of real blue quality!

Ignoring other crops, Ye Qiu held the long sweet potato vines and began to harvest sweet potatoes.

With a strong pull, big and plump sweet potatoes with moist soil popped out one after another.

Each one is the size of a forearm, and the largest one is as thick as Ye Qiu's calf!

Excluding the sweet potato vines, Ye Qiu estimated that the sweet potatoes harvested this time are at least thirty or forty kilograms!

The sweet potatoes planted yesterday ushered in the harvest today. The survival world really gives people endless surprises!

Clean the sweet potatoes and put them in the warehouse. Ye Qiu did not throw away the sweet potato vines and sweet potato leaves. He washed them, cut them and threw them directly into the broth pot.

Ye Qiu remembered that he had drunk sweet potato leaf soup when he was a child. The taste was still very good. It was just right to supplement some vitamins for his body that eats meat every day.

Tasting the saltiness of the broth, Ye Qiu added a little salt.

Turning the gas to medium heat, Ye Qiu came to the yard again.

The blue quality planting box is very precious, and it must not be left idle!

After replenishing the soil and water, Ye Qiu planted the sweet potatoes again.

Since the new sweet potato seedlings had not absorbed fertilizer, Ye Qiu added another portion, and the harvest date was changed to 24 hours later.

As for the seedlings in other planting boxes, Ye Qiu identified them through the survival manual and concluded that the fertility was about to be excessive.
